Is there a way to import a pdf into a default ID document then have it resize the document to the borders of the pdf?

No, at least not automatically.

But I think you are approaching this incorrectly. You don't necessarily need a plugin for ID. First, there is Print Booklet, already built in, that is the basic imposition mudule supplied withthe program. If you use a Mac with Snow Leopard or later you have to print to Postscript file and distill, though, as Apple killed the PDF virtual printer. (see InDesignSecrets » Blog Archive » Acrobat’s Adobe PDF Printer Replaced in Snow Leopard and read the commnets).

Tere are also some basic imposition scripts for ID that are free or donationware. My favorites are by Dave Saunders and work well for two-up saddle-stitch with no creep: http://pdsassoc.com/downloads/Buildbooklet.zip and Dave's CS3 Booklet Script. The first makes a new file and shuffles the pages, but does not work with cross-spine objects. The second creates a new docment with spread-size pages and places the orignal pages into that, so it does handle cross-spine, but it is slower.

I think you and I have different interpretations of "imposition" here. I'd call what you are doing an N-up layout (and I do the same as you -- step and repeat most of the time, when that's the goal) which I suppose is a type of imposition, but I don't see a connection to resizing a document to fit the placed PDF.

I cant afford to sit in front of the computer for extended periods of time laying out documents when I should be running the shop. I basically want to design the item I need then have the software to give me the option of how many I want on the page (with a preview so I can see how various sizes look) then have all the crop marks etc overlayed automatically.

For example I recently decided to distribute "Free Juice or Smoothie" vouchers to surrounding businesses. I had whipped up a quick voucher in Pages 09 that allowed 6 copies per A4 Sheet. I then had about a week of frustration as I was having printing errors with the document. It turned out to be a problem with the printer itself, but before I discovered that I came across Imposition Wizard. I don't why imposition software is considered only for proffessional use, it is probably more useful to the novice who cannot afford the time to learn manual proccess....

So now I have a new printer(a nice little fuji xerox) and I want to be able to quickly throw togeather what I need then open it in Imposition software so it can do all the time consuming stuff. Then I can print it out, hand it and a guillotine to a staff member then get on with the rest of my day.....

I see - there are a few free versions. Honestly though I think something like Quite Imposing (A plugin for Acrobat) would be better. It is $500 or thereabouts, but that's a one time expense and will severely clear up your time to run the shop.

Never heard of it before, but it looks interesting. It's not a plugin, however, but is clearly a script (which does not detract from the functionality). Why not try the 14 day demo and see if it works for you. I think we'd all like to know what you think.

Croptima at www.croptima.com was the best little imposer for Indesign for the money; however it seems they have decided to discontinue development and give their product away for free. I've been using it for years and it still works with the current versions of InDesign. I realize this is an old thread, but perhaps those stumbling back on it can use the freebie software that has become a favorite of mine. It does N-ups, front & backs, bleeds, cut stacks, books (both perfect bound and saddle) and even comes with a PDF placer that auto-adjusts and places your PDF files into Indesign for you. Great for placing those 100 page documents that you don't want to deal with page by page!
